The devoted couple also put up Christmas decorations together — they’re so cute!

Miley, 19, and Liam, 21, ate dinner at the Cyrus compound, along with familiar faces such as Miley’s brother Trace, his fiance Brenda Song, and her parents Billy Ray and Tish.

Tish posted a photo of the happy family to her Twitter, and we love that Liam is so welcome!

After the meal, Miley took to her own Twitter, writing, “I am doing some very serious x-mas decorating with Liam. Serious. Come check out my surfing Santa. It’s pretty epic.” This pair is TOO adorable!

What do YOU think, HollywoodLifers — are Miley and Liam the most down-to-earth couple in Hollywood?
